MR. McCLELLAN: You're talking about the transit without visa
program. That is something the Department of Homeland Security is
reviewing. At the same time, I think steps are already being taken by
the Department of Homeland Security to make sure that passengers on
these international flights receive closer scrutiny during the
screening process. But there are still people, killers, members of al
Qaeda that want to harm America and want to harm the American people.
That is why we are waging a global war on terrorism.

The best way to address this threat and to address these issues is
to go after these killers where they are and bring them to justice
before they can reach our shores and carry out such attacks. But we
have taken a number of steps to improve aviation security. We have
strengthened the cockpits by putting in bulletproof cockpit doors,
reinforced doors. We have taken steps to improve the screening process
by hiring federal screeners and passenger screeners. We have also
taken steps by putting federal air marshals on flights, as well, so
that the American people can know that we're doing everything we can to
protect them from these kind of threats.
